Specification of Letters Patent.

Patented July 2, 1912.

' Application filed November 14, 1910. Serial No. 592,321.

To all whom it may concern:

Be it known that I, IRA N. TERRILL, a citizen of the United States,residing at Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain new and useful Improvements in Wells, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

In certain localities the earths surface is underlain by a stratum ofquick-sand, or quick-sand and gravel, through which flows water, thisstratum always being underlain with clay, rock, or some stratumimpervious to water.

In wells heretofore used in obtaining water from water-bearing sand,trouble has been encountered in keeping quick-sand and silt from washinginto the well; and where water carries substances of cementingqualities-the sand immediately around the well becomes hardened intorock, thus partly or wholly'shutting off the water from the well. Anobject, therefore, of the invention is to overcome these difficulties.

Another object is to screen and filter the water as it flows into thewell.

Another object is to provide means for temporarily shutting out thewater and sand for purposes of cleaning or repairing the well. a

A further object is to afford access to the sand around and near thewell in order to break up and remove any solidified formation whichwould prevent a free flow of Water into the well.

Other objects and advantages of the invention will be set forth in theensuing description.

Referring to-the drawings: Figure 1 is a plan view of a well embodyingmy improvements. Fig. 2 is an enlarged sectional view, taken on ahorizontal plane near the bottom of the well. Fig. 3 is a perspectiveview showing a portion of the earth and a portion of the wall-of thewell broken away to expose construction. Fig. 4 is an enlargedperspective View of portions at the bottom of the well which are omittedin Fig. 5. is a sectional view on same scale as Fig. 2, taken on theline 5--5 of Fig. 1. Figs. 6, 7, and 8, are perspective views,respectively, of a gate, aniron frame, and a screen.

Referring to the several figures, in all of which like characters ofreference designate like parts, the earth formation herein shown has astratum 9 of quick-sand underlying the upper stratum 10 of soilformat-ion. This stratum 9 of quick-sand is underlain by a stratum 11 ofimpervious clay or rock, and when this stratum of clay or rock is not attoo great a depth to be reached it forms the bottom of the well. Whenthis impervious stratum 11 is at too great a depth, a bottom 12 ofmasonry, concrete, sheet steel, or other material impervious to water isfooted in the quick-sand stratum 9 to support other parts of the well.

The 'well is provided with an outer wall 13 of concrete, masonry, orother suitable material, this wall resting upon the edges of the bottom12. The lower edge of the wall 13 is provided with a number of openings14, of which there are sixteen in this instance, the lower edges ofthese openings being the upper surface of the bottom 12. The upper edgeof each opening 14 is provided with lintel bars 15 and 16 which act as areinforcing support for the wall, 13 above it. These lintel bars 15 and16 are notcircular, but extend as a chord to the curvature of the wall13, the inner one 15 forming. an outer guide for a verticallymovablegate 17 later described, so that the central portlon of said gate clearsthe inner surface of said wall in moving vertically.

The wall 13 is provided with buttresses 18 between the openings 14, theside faces 19 of said buttresses standing on radial lines of the welland being an inward continuation of the sides .20 of said openings. Theupper ends of the buttresses 18 are preferably horizontal, so that theymay support any scaffolding that may be used while cleaning or repairingthe well. In order to close the openings 14 against the entrance ofwater and sand while cleaning or repairing the well, each opening isprovided with the sheet-iron gate 17 aforesaid, which is arranged toslide vertically along the inner ace of the wall 13 in contact with theinner lintel bar 15. The upper edge of the outside-surface of this gate17 is provided with a metal cleat 21 having a beveled lower edge, so asto fit tightly againstthe inner lintel buttresses 18 and in thebottom'12, the gate being provided at its upper edge with a verticaloperating rod or handle 23* fo'r opening and closing it.

A screen 24, shown separately in Fig. 8,

. is mounted inwardly of the frame 22 in each opening 14, and is heldoutward against said frame by iron pins 25 embedded in the buttresses18, wedges 26 beinginserted down between said pins and screen to clampthe latter againstsaid frame. Each screen'24 consists of two iron frames27 and 28 with wire screen 29 interposed between them, this screen beingso thin that it does not show in the sectional views, and bolts orrivets 30 extend through said frames and screen to clamp thempermanently together. A second or inner screen 31, similar to the outerscreen 24,-is mounted removably in each opening 14, and the spacebetween said inner and outer screens is filledwith charcoal 32 or anyother suitable filtering substance, a small amount of this filteringsubstance being. omittedinFig. 5 to expose the pin 25 and wedge 26 abovereferred to. In packing this filtering substance in, the inner screen 31is crowded inwardly of the'well until stopped by wedging the convergingsurfaces 19 of its adjacent buttresses 18. The'filtering substance 32 iscovered by a sheetiron plate 33 which fits between the convergingsurfaces 19 of the buttresses 18, the inner edge of this plate restingupon the inner screen 31 while its outer edge rests upon the upper edgeof the frame 22 and in contact with the upper art of the gate 17. Thisplate 33 is1he1d dbwnward onto' the screen 31 and frame 22 by ironpins34 embedded removably in the buttresses 18, wedges 35 being insertedbetween said pins and plate to clamp the latter against said screenand-frame.

fter the screens 24 and 31 havebeen set- A in Iplace, and the filteringsubstance 32 pac ed between them, and after the plate 33 has been put inplace over said filterin substance and clamped down as describe the gate17 is opened upward, allowing the water and'sand outside to flow'againstthe outer's'creen 24 and allowing the water to flow through said screen,through the-filtering substance, and through the inner screen 31 to fillthe well. I

To clean the well, the gates 17 are closed downward against the om 12,the lower edges of said gates being sharpened in order 'to pass downeasily through the sand outside of :the frame' 24. After closing thegates 17 the plates 33 are removed fromplace and the filtering substance32 dug or removed from between the screens 31 and 24. These screens 31and 24 are then removed and the well cleaned or repaired, one

gate 17 at a time being opened upward tem;

any solid-formation immediately outside of said gate. After cleaning thewell, the screens 24 and 31 are set in place and fresh filteringsubstance 32 packed between them, the plates; then being put in placeand fastened; lie -gates 17 are then opened and the well fills withwater which is puri fied by passing in through the screens andTheforegoing being a;;fu]l, clear, and, exact description of theinvention, what I claim and desire to secure by Letters Patentisz- 1.
